Heritage-inspired tank graphics and an FXRT-style fairing look retro, but the Low Rider ST is a modern performance motorcycle with a new Milwaukee-Eight® 117 High Output V-Twin Engine.

Design
FXRT roots, reimagined. The Low Rider ST cuts a fierce profile with a West Coast–inspired fairing and new all-LED lighting. A modern take on a classic silhouette that blurs the line between retro cool and today’s comfort and performance.

Inspired by West Coast customizers who embrace the classic FXRT fairing, the Low Rider ST’s lightweight, frame-mounted fairing is developed using computational fluid dynamics (CFD) to improve airflow—helping reduce wind fatigue for a more comfortable, stable ride.

A 146 mm headlight, redesigned taillight, and LED turn signals improve visibility and signalling on the road.

Premium paint and retro-inspired graphics highlight H-D’s iconic design heritage.
The slim solo seat holds you in place during aggressive acceleration and cornering.

Performance
More power delivered quickly from the new Milwaukee-Eight® 117 H.O. V-Twin Engine with Heavy Breather intake and a redesigned two-into-one exhaust.

A tall monoshock kicks up the rear end and provides extra cornering clearance when you are pushing the limits.

Improved mid- and top-end performance from the Milwaukee-Eight® 117 H.O., which lets you stay on the gas longer during hard acceleration, with redline pushed from 5,600 rpm to 5,900 rpm.

A sleek and refined exhaust line brings saddlebag symmetry, extra storage, and a timeless, cohesive look—setting the stage for customization upgrades.

Forward-facing air intake maximizes flow and provides intake tuning length to improve charging efficiency and peak torque.

Innovation
Customize your ride with three available ride modes and the full suite of Rider Safety Enhancements, all accessible through a new four-inch instrument display.

New hand controls feature Ride Mode selection, a repositioned flash-to-pass switch near the left forefinger, and an adjustable brake lever.

An analog speedometer with a built-in multi-function digital display provides key ride data, including a gear shift indicator and new selectable Ride Modes (Road, Rain, and Sport), so you can fine-tune your ride like never before.

USB-C charging keeps your devices powered, so you can ride farther while using navigation, listening to music, and staying connected through your Bluetooth® headset.

Rider Safety Enhancements
Harley-Davidson’s Rider Safety Enhancements is all about giving you that extra peace of mind when things get a little unpredictable. It’s a set of smart tech that steps in during tricky situations, helping the bike handle traction while you’re accelerating, braking, or slowing down. With the Cornering Rider Safety Enhancements, the bike even adjusts for cornering, keeping things smooth and steady without you having to think twice.
